refactor(silencer): stop guarding work that stays inside Rust

Silencer only lowers the PHP error_reporting() level and re-throws
whatever the guarded work raises. A region that never reaches the PHP
runtime has no level to lower and emits no diagnostic on failure, so
wrapping it is indistinguishable from running it unguarded.

The pair kept in Application::hint_common_errors brackets a
getComposer() call, which loads installed plugins and dispatches
PluginEvents::INIT.
